PLOW.

To all whom it mag concern:

Be it known that I, CHARLES T. RAY, a citizen of the United. States, residing at Louisville, in thecounty of Jefferson and State of Kentucky, have invented new and usefullmprovements in Plows, of which the following is a specification.

This invention has relation to plows or plow bodies, hereinafter for convenience called plows.comprising a frog, a share and a landside, and one'of the most important objects is to soformand correlate these parts that they mutually brace each other and cooperate to form a plowof exceptionally rig'id and wellubalanced construction. In other words, .one of the most important objects of the invention is to provide a novel construction of .the various parts of a plow and. an improved manner of fitting these parts together whereby the rigidity neces sary to preserve the pitch, balance and durability of the plow is insured and theparts are held firmly in place and lptrlevented from becomingfloose or shaky. other important purpose is to so construct and correlate the parts that the strains due to plowing will'not be transmitted to the bolt used to connect the share to the frog. r

Theseobjects and others which will be understood by those familiar with this invention and. the art to whichit relates, are well secured by the construction illustrated in theaccompanying drawings, and which construction has been'selected asexemplifying thebest embodimentof the invention now known to me. 1 It should be understood, however, that changes in the details may be made without departing from the spirit of the invention or the scope of the subjoined claims. I 1 t H In the drawings, wherein like characters of reference, designate corresponding parts in the vdiflerent views: 7

Application filed August 11, 1913. Serial N 0. 784,113.

: Referring to the drawing in detail, the in-. vention comprises a frog .A, landside .13, share C and moldboard D.

The frog is of angleconstruction including the substantially straight landside side Band a wing 6, which wing is laterally inclined and rearwardly divergent from the front end of the side 5, the correlation of the side 5 and wing 6 "being such that-the front end 29 of the frog is substantially pointed. This frontend, moreover,is rearwardly inclined upward from the lower end of the frog. At the junction of the lower front ends of the side 5 and wing 6 a nose 7 is formed. The lower portion of the outer face of the landside side5 of the frog is formed. with a longitudinally extending recess or cut away portion 8 to receive the landside B, whose forward edge is thus alined with and forms substantially a continuation of the front edge of the frog thereabove. This landside B has its lower rear portion or heel flanged as usual, the forward end of the flange gradually merging into the. lower edge of the forward part or toe of the landside, as' shown at 10". The upperedge 10 of the landside B engages the shoulder 9 formed by the recess 8. The landside B is held against the landside side -5*of the frog by suitable means-as bolts 11, for exampleand'is prevented from risin by the shoulder 9. The lower edge of the forward portion of the frog has a projection 5? which extends to the horizontal plane of the bottom surface of the flange of the landside B, the rear portion of the frog'resting upon the upper surface of the flange of the landside, as clearly shown in Fig. 1..

The share C is pointed as usual,.and includes alandside side 12 which is flush with the outer surface of the landside B when the parts are assembled. It also includes a rearwardly divergent, laterally inclined wing 13 which rests upon the wing 6 of the frog and in practice is preferably connected thereto by a suitable element as the bolt 14, for eX- ample. It may be here mentioned that this bolt is not essential in holding the share in position :while plowing, and is employed merely to hold the share against the frog and landside when the plow is moved backward against a resisting substance: the frog, landside and share being mutually formed to provide at their contiguous portions, lugs forming shoulders, or the like, presently to be described, which engage each other and hold the share in position, the correlation of the parts being such, moreover, that the strains due to plowing will not betransmit ted to the bolt 14. V

The moldboard D is suitably secured to the wing 6 of the frog and its forward edge conforms in shape to and'engages the rear edge of the share C, the latter as clearly shown being curved. A bolt 15 constitutes a suitableineans "for securing the 'holdboard D to th wing of the frog: and the. rear. end

of the moldboard is held against lateral movement by abrace 16 which is secured to the 'moldboard and to the landside'B.

fIn order to'rigidly connect the parts, I have constructed the plow so that the share will be interlockedwith both-the frog and the landside; Tothis end the lower edge of the wingf6-of the frog isformedwith a notch or seat" 17 the landside side of the nose 7 ofthe frog has a recess 22' with allug 21 at the rear end thereof: the for:

Ward end 28 of the landside B, which subside'of the frog and in the landside, and

engages beneath thevlugs 21 and 26. The

width of the lug 20 is substantially equal to the combined thickness of the lugs 22 and 26.

Thesl are C further comprises a shin 27' one side 'of which consists of a wall 24:.

which forms a continuation or extension of and lie s in the plane of the landside side 12 of the share and the o therside of which forms a continuation or extension of the wing .13.. At its upper end the shin 27 carries a. rearwardly pro ecting shoulder which engages a shoulder 31 formed by the upper front corner -.ofthe frog A. The

share is formed with a rearwardly facing:

abutment 28 which extends from the shoulder '30 to the lug 20 and lies substantially at right angles to the landside face of the share: The upper part of vthis abutment:

is curved to conform to the shape of the front edge-of the upper portion of the frog and its lower part conforms to-the shape of the forward end'23 of the landside B;

. said abutment, when the parts are. assembled lying against said parts of the frogand landside.

It will therefore, be seen that when-the parts are brought into assembled relation the rear face of the wing 13 ofthe'share lies against the front face of the wing 6 of the frog with the shoulder formed by the lug 20 complementally engaged by the shoulders formed by the lugs 21 and'26 and with the lug 18 of the share engaged with the seat 17 of the wing of the frog. The parts are further interconnected by the engagement of the shoulder 30 with the shoulder 31 lnaddition the rearwardly facing'abutrecess 22 the nose/(of thefro'geenters the 8 5' space 19 formed betweenthe lug20' and the rear face of the lower portion' of the wing 13. a 4' v V Consequently, .it will be seen that the structure is. such as tosecure the 'parts efe fectually in assembledrelation and transmit the strainbrought upon the share in plowing tozthe frog withpractically no strain whatever 1 upon. thelbolt' 14, said bolt serv ing, as before stated, merely to hold the share against movement away from the wing 6 when the. device is not in use or when the plow is pulled rearwardly, 7 I
